The UFC fighter is as famous for his concussive striking power as he is for his memorable microphone skills, his flambouyant dress sense, and his taste for a night on the town. He plays hard, but he trains even harder. McGregor won titles in Cage Warriors, transitioned into premier cage-fighting firm UFC, and continued to trounce his opponents.

But to return to sporting dominance, he has to eat right. So what sort of food does a former two-weight UFC world-champion fighter eat?

Here's everything McGregor likes to have for breakfast, lunch, and dinner.

This is Conor McGregor, the former two-weight UFC champion renowned for his pre-fight trash talk, his highlight-reel striking, and his flashy lifestyle. After two years away from mixed martial arts, McGregor returned to the sport but was submitted by Russian wrestler Khabib Nurmagomedov at UFC 229.

McGregor, who is already plotting his comeback, projects a work-hard, play-hard image. When it comes to training camp and cutting weight, he may well be an advocate of the "Sirtfood diet," having taken a photograph holding a copy of the book by Aidan Goggins and Glen Matten. The weight-loss diet involves foods that are rich in "sirtfoods" — typically, things like green tea, 85% dark chocolate, and citrus fruits.

Conor McGregor starts his day just like we do — he wakes up and reaches for the coffee. Unlike most, though, he drinks it while looking fresh in a suit.

A typical breakfast for McGregor involves eggs, and his coffee of choice is an Americano, which is a shot of espresso diluted with hot water. "I eat eggs — an omelet with my Americano for a late breakfast or brunch," he reportedly told AskMen in 2016.

As an athlete, McGregor's diet is relatively clean (with one or two exceptions), and includes fresh fruits. One good way to get your daily fill of fruit is to enjoy a bowl of it on board a private jet.

Fruit isn't the only thing McGregor eats at altitude, as he also snuck in a meal en route to a family vacation in Ibiza. With his young son sitting next to him, McGregor appears set to devour a salad with protein and greens. If those greens are kale, then McGregor is adhering to that "Sirtfood diet."

McGregor doesn't just like to eat and drink on planes, though. No. He also digs into lunch while on a speed-boat…

...Where he's also been known to knock back a brew in the middle of the day. Here, in a photo taken last October, he drinks a Budweiser in celebration of the Ireland soccer team progressing into a playoff spot to qualify for the 2018 World Cup tournament.

He's even enjoyed a meal just outside his VIP box at the 2018 FIFA World Cup final, shortly before he met Russian president Vladimir Putin.

Rehydrating is just as important as fuelling and McGregor will drink protein shakes, plenty of water, and even coconut water. "Getting enough protein is important when I train, to help build muscle and recover, so I’ll supplement with protein shakes," he reportedly said.

McGregor doesn't tend to load-up on carbs, but when he does, he makes one exception. "I don’t eat a lot of carbs — if I do it’s something like sweet potatoes."

McGregor loves landing combinations in a UFC cage, but at dinnertime, it's all about a combination of foods. Here, in a Versace robe, he tucks into roasted chicken, green salad, what appears to be mashed potato, and root vegetables. He even, apparently, said the following prayer: "May god shine his blessings down upon this beast, about to devour his feast. And may thy people say the very least about this absolute beast or they will end up in a box deceased." A… Amen?

McGregor also dines out, and seems to favour Japanese restaurants. Here, he digs into some sushi — and If the pot has green tea in it, then he, again, is enjoying at least one sirtfood-rich item.

McGregor works hard, we all know that. But he also plays hard, and we probably all know that, too. Here he is at what could be the end of a night, drinking a cold one with a mate who may well have necked tequila straight out of the bottle.
